Flashcards in Pelvis/LE - Hip and Pelvic Girdle Joints Deck (16):
1

Hip Joint

synovial joint
ball and socket
acetabulum of the pelvic girdle to the head of the femur

2

Angle of Inclination

angle of the neck to the shaft of the femur
115 - 140 degrees normal

3

Angle of Torsion

angle of head and neck of femur to distal condyles of femur
7 - 12 degrees normal

4

Joints of the Bony Pelvis (4)

lumbosacral
sacroiliac
sacrococcygeal
pubic symphysis

5

Lumbosacral Joint

between L5 and S1
articulate anteriorly at the anterior intervertebral joint formed by the L5/S1 disc and posteriorly between two zygapophysial (facet) joints between the articular processes
pelvic girdle

6

Lumbarization

S1 not fully fused to S2
looks like 6th lumbar vertebrae
causes hypermobility

7

Sacralization

L5 fused to S1
causes hypomobility

8

Sacroiliac Joint

joints between the sacrum and the ilium
anterior portion synovial
posterior portion syndesmosis
links skeleton to trunk

9

Zygapophysial Joints

Facet joints
different angles throughout spine
C-Spine: hands on shoulder
T-Spine: hands on back
L-Spine: hands on hips

10

Ligaments of SI Joint (5pair)

anterior sacroiliac ligaments
interosseous sacroiliac ligaments
posterior sacroiliac ligaments
sacrotuberous ligaments
sacrospinous ligaments

11

Interosseous SI Ligaments

primary structures of force transfer from axial skeleton to the two ilia and then femurs during standing and ischial tuberosities during sitting

12

Pubic Symphysis

secondary cartilaginous joint
located at union of the bodies of the pubic bones

13

Sacrococcygeal Joint

secondary cartilaginous joint between sacrum and coccyx
sacrococcygeal ligaments
no known function, but can cause pain if rotated (post rot easier to fix)

14

Function of Sacrotuberous and Sacrospinous Ligaments

allow only limited upward movement of the inferior end of the sacrum

15

Ligamentum Teres

comes out of head of femur and attaches to acetabulum
blood supply in children then turns to ligament later

16

Labrum

fibrocartilage that makes socket deeper
